AFC Cup

The AFC Cup began in 2004 as a second-tier competition to relate back to the AFC Champions League as 14 countries that had developing status competed in the first competition with 18 teams being nominated. Group A, B, C had West and Central Asian teams while the other two groups had east and South East Asia. The winners and three runners-up would then head to the knock-out stage where it was a random draw in who was going to play. Al-Jaish took the first AFC Cup after they defeated fellow Syrian opponents Al-Wahda on away goals.

In 2005, 18 teams competed from nine nations with the nations still being allowed to choose from one or two teams entering. After Syrian teams left the AFC Cup to try at the AFC Champions League for four years, Al-Faisaly defeated Nejmeh in the final. With it, Jordanian teams would win the next two AFC Cup seasons with Bahrain joining the league while Bangladesh was relegated to the AFC President's Cup until the tournament's abolition in 2014.

Al-Muharraq would break the trend in 2008 as they competed in the last two-legged final before it headed back into a one-leg system, a rule that was never changed till the termination of this tournament.

On 23 December 2022, it was announced that the AFC competition structure would change from the established formats from the 2024–25 season. Under the new plans, the AFC Cup was discontinued, and a new second-tier tournament called the AFC Champions League 2 was introduced. Meanwhile, a new third-tier competition was also launched under the name AFC Challenge League.
